Krone’s new direct-cut header, the XDisc 710, has more than 7m working width and the option of an integrated transport chassis, and is designed for added efficiency and comfort, according to Farmhand.
In addition to maize, whole crops have become popular in recent years. Used in biogas and animal forage, these crops require optimum quality harvesting with increasingly powerful forage harvesters. The new XDisc 710 meets all these challenges, according to Farmhand, thanks to a range of technical modifications, and its increased working width of 7.10m, compared to the 6.20m offered by the XDisc 620.
The cutterbar of the new XDisc 710 is also based on the Krone EasyCut mower technology. Thanks to the perfect overlapping of the blade paths guaranteed by the SmartCut system, you can achieve optimum-quality, stripe-free cutting everytime. With the help of SafeCut, the cutting disc is jacked up in the event of contact with a foreign object. This makes sure that it does not come into contact with neighbouring cutting discs and avoids extensive damage to the driveline. The cutterbar is equipped with integrated quick-change blades to reduce any downtime. In the XDisc 710, these cutterbars are gear box driven ensuring no slip or loss of drive in the chopping process, even at high throughput the unit will deliver very even cuts, which is one of the key factors for optimum chop quality.
With its large diameter of 900mm, the feed auger is designed for high throughput. The speed of the auger conveyor can be adjusted to the intake speed of the forage harvester in three stages, depending on the cutting length of the crop. The basic height of the auger conveyor can also be adjusted manually in three stages using eccentrics to allow the crop to pass through. The freely movable auger conveyor can also easily move upwards when handling bulky crops. Together with the crop press roller unit, this ensures an even crop flow.
The perfect interaction of cutterbar, auger conveyor and crop press roller unit significantly reduce speed peaks in the drive. This brings impressive benefits, according to Farmhand: lower power requirement per metre of working width and savings of up to 10 per cent diesel fuel (litres per tonne) with around 20 per cent higher throughput (tonnes per hour) compared to the XDisc 620.
